The three designs — “Biomimicry”, “Technology”, and “Trends in Society” — differ aesthetically but function in a lot of the same ways. They all include pleats of some kind as well as electroluminescent wire, but their respective designs are influenced in different ways. More on the three suit designs, including 3D models for each, is available on NASA’s website. A Z-2 suit is expected to be completed by November 2014.
